MACHINE FOR CUTTING SHOVEL-BLANKS.

SPECIFICATION forming part of Letters Patent No, 385,820, dated July 10,1888.

Application filed April 3, 1888. Serial No. 269,417. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY M. MYERS, a citizen of the United States,residing at Beaver Falls, in the county of Beaver and State ofPennsylvania, have invented certain new and useful Improvements inMachines for Cutting Shovel-Blanks; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to the art of shovelmaking, and has for its objectan improved machine for cutting blanks from cold bars of iron or steel.

In the manufacture of shovels made from blanks cut from heated bars theblank cutting machine supplies blanks faster than they can be split andreduced by the remaining machinery without reheating the blanks. Toreheat the blanks involves the expense of two extra worlunembesides thefuel consumed. It is my purpose to cut the blanks from cold bars of ironor steeland heat them in such quantilies as will supply thesplittingmachine and the rolls.

The invention will be hereinafter described, and particularly pointedout in the claim.

In the accompanying drawings, which form part of this specification,Figure 1 represents a front elevation; Fig. 2, an inverted plan of thesaddle attached to the reciprocating head; Fig. 3, a plan of the saddleattached to the base of the machine; Fig. 4, a perspective of portionsof the upper and lower cutting-dies detached; Fig. 5, a perspective of ablank cut from a bar, and Fig. 6 a similar view of a bar with blanksindicated in dotted lines.

Reference being had to the drawings and the letters marked thereon, Arepresents an ordinary cutting or punching machine, which may beprovided with a stop-motion or may be run under a continuous motion.

B is a reciprocating head, to which is de tachably secured a saddle, O,by belts or, and to the saddle is adjnstablysecured a cutter or die, b,by clamping-bolts c c, and a gage, d, which fits into the rectangularrecess in each blank D between the tang c and the end of the blank, andputs the bar into properposition for the die to sever the blank from it.To the base E of the machine is also detachably secured a saddle, F, byboltsf, and in the anvil G of the saddle is adj ustably secured a die,g. which corresponds with the die Z) in the head B. The saddle F alsosupports guides h i, which are secured in position by bolts is Z, andbetween which the bar H is fed under the die b.

On the end of the base E, and in line with the groove m, in which thebar H lies, is a roller, 41, upon which the bar rests While it is beingfed into the machine. By securing the dies adjustably they may be set tocut clear and clean, and different-sized dies or cutters may be appliedfor cutting different-sized blanks, and by making the saddles detachablethey may be readily removed for replacing any of the parts that are wornor broken.

The bar H is turned after each blank is cut therefrom. Blanks for otherimplements may be cut by the machine by changing the form of the dies.

Having thus fully described my invention, what I claim is- A machine forcutting shovel or other blanks, provided with a reciprocating head, adetachable saddle secured to said head and provided with a cutting-die,in combination with a detachable saddle secured to the base of the ma--chine and provided with an anvil, the die, and gages, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
